Blavatsky correspondence

Helena Petrovna Blavatsky conducted an extensive correspondence throughout her life. She was perfectly proficient at writing in Russian, in French, and in English.

Letters to A. P. Sinnett

A. Trevor Barker compiled The Letters of H. P. Blavatsky to A. P. Sinnett. The original letters are now in the British Library. The text has been made available online by the United Lodge of Theosophists - Phoenix, Arizona and at Theosophical University Press Online.

The Judge letters

William Quan Judge made what is probably the first compilation of HPB's correspondence in The Authentic Letters of H.P.B., As Edited by One Of the Main Founders of the Theosophical Movement, available online at Esoteric-Philosophy.com.

Collected letters

Boris de Zirkoff, Dr. John Cooper, and then Dr. John Algeo, collected the letters and and organized them in chronological order. Some of the letters have been published in a first volume by Dr. Algeo in 2003.

A great deal of additional work is yet to be done in what promises to be a long series of books of HPB's letters. It is unknown at present who will continue the project since Dr. Algeo's retirement.
